Aluminum is used as a basic metal or as an alloy for utensils, engineering, electrical equipment, cooking foil, and canning; where lightness, cheapness, tensile strength or conductivity are factors in design.Aluminum (aluminium) is used in a variety of industrial, structural, and consumer applications.he ancient Greeks used alumina as a medicine, and alum (potassium aluminum sulfate) still has some use as an astrigent, along with aluminum sulfate. Aluminum hydroxide is an antacid. Aluminum phosphate is used in some cosmetics as an anti-perspirant.

Alum for Pickling 1 Shaving alum is a powdered form of alum used as an astringent to prevent bleeding from small shaving cuts. 2  The styptic pencils sold for this purpose contain aluminium sulfate or potassium aluminium sulfate.3  Similar products are also used on animals to prevent bleeding after nail-clipping. Typically potassium alum is used. 2  Water treatment-Alum (aluminium sulfate) is used in water treatment. 3  The addition of alum to raw water causes small particles and colloids to stick together and form heavier particles (floc) which will settle in water.

Alkaline earth metal The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium, magnesium, calcium, strontium, barium, and radium. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. Structurally, they have in common an outer s- electron shell which is full; that is, this orbital contains its full complement of two electrons, which these elements readily lose to form cations with ch

Why are alkali metals very reactive? 2.5k Views. Alkali metals are known for being some of the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and often have an oxidation state of +1. These metals are characterized as being extremely soft and silvery in color.

It's Elemental Lithium is the lightest known metal and can be alloyed with aluminium, copper, manganese, and cadmium to make strong, lightweight metals for aircraft. Lithium hydroxide (LiOH) is used to remove carbon dioxide from the atmosphere of spacecraft. Lithium stearate (LiC 18 H 35 O 2) is used as a general purpose and high temperature lubricant. Lithium carbonate (Li 2 CO 3) is used as a drug to treat manic depression disorder.

Why are alkali metals and alkaline earth metals very reactive? Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where … as alkaline-earth metals need to give two away which is less energetically favorable.

- The alkaline earth family is the second most reactive group, and it's elements can't be found free in nature. They are called alkaline earth metals because they form alkaline solutions, hydroxides, when they react with water.This term Alkaline means that the solution has a pH greater than seven and is basic. Thus, the alkaline earth metals form very basic solutions and are excellent reducing agents.he alkaline earth family is the second most reactive group, and it's elements can't be found free in nature.
